Over the past 40 years, Jim Cummins has proposed a number of highly influential theoretical concepts, including the threshold and interdependence hypotheses and the distinction between conversational fluency and academic language proficiency. In this book, he provides a personal account of how these ideas developed and he examines the credibility…

Research on issues concerning the assessment of school-age English language learners (ELLs) in curriculum-learning contexts has been relatively less productive than assessment of adult language learners. A growing demand for assessing school-age ELLs has led to the development of assessment frameworks that provide the opportunity to examine the…

This study examined university undergraduate English language learners' (ELLs) perspectives on an intervention, Word Matters, that aimed to enhance functional academic vocabulary learning critical to their cognitive academic language proficiency development (Cummins, 1989), a challenge faced by many ELLs in English-medium universities. This…

This article attempts to provide ESL teachers, school administrators, and policymakers with a concise overview of what matters in promoting academic success among learners of English in Canadian schools. We review research focused on bilingual and biliteracy development, the nature of academic language, and the roles of societal power relations…

The present paper synthesizes the international research literature on the educational achievement of immigrant and minority language students by articulating three propositions for which there is strong empirical evidence: (a) print access and literacy engagement play a key role in promoting reading comprehension; (b) the development of bilingual…

Elaborates on cognitive/academic language proficiency and basic interpersonal communicative skills. Discusses assumptions regarding bilingual program exit and entry fallacies and implications for U.S. bilingual education. Argues that failure to adequately conceptualize the construes of language proficiency and its cross-language dimensions causes…

The state of the art of research in second language acquisition is reviewed. A framework is first established for the examination of second language learning. The concept of proficiency is addressed with respect to its theoretical basis, rating scales, formal tests, and interlanguage studies. The social context of second language acquisition is…

A study was designed to investigate the nature of language proficiency and its cross-lingual dimensions. The focus of the study was on the interdependence hypothesis, that older immigrant students whose first language (L1) cognitive/academic proficiency is better developed on arrival in Canada will acquire English cognitive/academic skills more…

A bilingual education teacher training packet (student's edition) on theories and research concerning bilingual education, second language acquisition, and communicative competence is presented. A theoretical framework for integrating these theories and a theoretical rationale for bilingual education are also presented. In addition to…

It is argued that cognitive/academic language proficiencies in first and second languages are interdependent and empirically distinguishable from interpersonal communication skills. This analysis is applied to the interpretation of data on the effects of bilingual education programs and on the age issue in second language learning. (PMJ)

Recent research and program evaluations show that the poor academic performance of many bilingual children was caused not by their bilingualism but by the school's attempts to eradicate that bilingualism. These findings demonstrate that bilingualism can positively affect minority children's development when their first language is promoted by the…

The debate over the past decade about the pedagogical effectiveness of bilingual education and the research evidence are reviewed. The case for bilingual education rests on the assumption that because children cannot learn in a language they do not understand, they will fall behind academically in programs taught only in that language. Against…

The observations of educators and educational research have shown that academic outcomes for minority groups exposed to the same educational programs are different. The phenomenon does not seem to be due to superior intelligence, social class, or length of time in the country. Documented since the mid-1960s, this should be taken into account when…

Identifies four misconceptions about language proficiency which are currently impeding the implementation of effective bilingual education programs. Misconceptions involve: (1) surface structure deviations and academic achievement; (2) surface fluency and "English Proficiency"; (3) bilingual language proficiency and instruction; and (4)…
